service.
Follow one of the 3 scenarios below to determine where the
R32 sensor needs to be connected to:
Scenario 1: Amana® Brand / Goodman / Daikin Furnace
PCB with R32 sensor compatibility.
The leak detection sensor must be wired directly to the
furnace. Follow routing diagram as shown in Figures 4 or
5 depending on orientation of install. This wiring is intended
to be passed through the access hole on the furnace. If a
hole must be cut into the furnace, ensure that the wiring is
well protected from mechanical damage and that the hole is
free from burrs or sharp edges. Utilize a protective coating
for all exposed metallic edges to prevent corrosion. Verify
that the A2L function (this is required for R32 integration)
is enabled on the furnace board PCB. Refer to the furnace
IO for further instruction on how to toggle this function
described on the furnace IO must be completed before
the unit is commissioned. If the test is not successful, call
1-855-DAIKIN1, option 3, for further assistance.
Scenario 2: Amana® Brand / Goodman / Daikin Furnace or
Modular Blower PCB with no R32 sensor compatibility.
The leak detection sensor must be wired directly to the NonA2L Furnace Integration Kit and installed as a pass-through
to the non-A2L furnace control board. For instructions on
how to correctly wire the Non-A2L Furnace Integration Kit
refer to the kit IO.
This appliance is equipped with a leak detection sensor
which must be wired through the connector on the furnace
PCB or Non-A2L Furnace Integration Kit.
The R32 Sensor must be installed and powered for service.
Ensure that the grommet is installed through the access
panel knockout hole. Sensor bracket assemblies are
shipped with two zip ties, one of which is designed for strain

WARNING
WARNING
11.1 Standing Pressure Test (Recommended before
vacuum)
Using dry nitrogen or dry helium, pressurize the system to
460 PSIG. Allow the pressure to stabilize and hold for 15
Minutes (minimum). The system is considered leak-free
if the pressure does not drop below 460 PSIG. If, after 15
Minutes, the pressure drops below 460 PSIG, it implies a
leak in the system. Proceed with identifying and sealing
the leak and repeating the Standing Pressure Test. Leak
test the system using dry nitrogen or dry helium and
soapy water to identify leaks. No refrigerant shall be used
for pressure testing to detect leaks. Proceed to system
evacuation using the Deep Vacuum Method.
11.2 Deep Vacuum Method
The Deep Vacuum Method requires a vacuum pump
air and moisture. The Triple Evacuation Method is
detailed in the Service Manual for this product model as
an alternative. To expedite the evacuation procedure, it is
recommended that the Schrader Cores be removed from
the service valves using a core-removal tool.
WARNING
NOTE: Refrigerant tubing must be routed to allow adequate
access for servicing and maintenance of the unit.
Doing so may result in damage to the tubing joints. Always
use clean gloves for handling coil assemblies.
Follow standards related to ASHRAE 15, ASHRAE 15.2,
IAPMO Uniform Mechanical Code, ICC International
Mechanical Code or CSA B52 during any installation. Piping
must be accessible for inspection prior to being covered or
enclosed in compliance with national and local codes.
The indoor equipment and pipes must be securely mounted
and guarded such that accidental rupture of equipment
cannot occur from such events as moving furniture or
reconstruction activities. Field-made refrigerant joints
indoors shall be tightness tested. The test method shall have
a sensitivity of 5 grams per year of refrigerant or better under
a pressure of at least 0.25 times the maximum allowable
pressure. No leak shall be detected (Should be leak tight).
Field pipework must be pressure tested with an inert gas and
then vacuum tested prior to refrigerant charging according
to the following requirements:
1. Connect the vacuum pump, micron gauge, and
vacuum-rated hoses to both service valves. Evacuation
must use both service valves to eliminate system
mechanical seals.
2. Evacuate the system to less than 500 microns.
3. Isolate the pump from the system and hold the vacuum
for 10 minutes (minimum). Typically, pressure will rise
slowly during this period. If the pressure rises to less
than 1000 microns and remains steady, the system is
considered leak-free; proceed to system charging and
startup.
4. If pressure rises above 1000 microns but holds steady
below 2000 microns, non-condensable air or moisture
may remain, or a small leak may be present. Return to
step 2: If the same result is achieved, check for leaks and
repair. Repeat the evacuation procedure.
5. If pressure rises above 2000 microns, a leak is
present. Check for leaks and repair them. Then, repeat
the evacuation procedure.
11.3 Tubing Size/Length

spun closed suction line.
Installation of pipe-work must be kept to a minimum. Pipework including piping material, pipe routing and installation
must be protected from physical damage and shall not
be installed in an unventilated space. Equipment piping
in any occupied space shall be installed in such a way to
protect against accidental damage in operation and service.
Precautions must be taken to avoid excessive vibration
or pulsation to refrigeration piping. Protection devices,
danger of water collecting and freezing in relief pipes or the
accumulation of dirt and debris. Steel pipes and components
shall be protected against corrosion with a rustproof coating
before applying any insulation. Any solenoid valves and
piping in the refrigerant systems must be so designed
and installed to minimize the likelihood of hydraulic shock
damaging the system. Solenoid valves must not block in
liquid refrigerant unless adequate relief is provided to the
refrigerant system’s low pressure side. Provisions must be
made for expansion and contraction of long runs of piping.
WARNING
11.5 Brazing
Braze joints should be made only with the connections
provided external to the cabinet. Do not alter the cabinet
nor braze inside the cabinet. To avoid overheating after
brazing, quench all brazed joints with water or a wet rag.
This system must be charged with R32 refrigerant in
order to operate safely.
When breaking into the refrigerant circuit to make repairs
– or for any other purpose – conventional procedures
it is important that best practice be followed, since
shall be adhered to:
refrigerants purging shall be achieved by breaking the
vacuum in the system with oxygen-free nitrogen and
to a vacuum (optional for R32). This process shall be
repeated until no refrigerant is within the system (optional
used, the system shall be vented down to atmospheric
pressure to enable work to take place.

It has been determined that many coil cleaners and drain
pan tablets contain corrosive chemicals that can be harmful
time application of these corrosive chemicals can cause
premature aluminum evaporator coil failure. Any cleaners
that contain corrosive chemicals including, but not limited
to, chlorine and hydroxides, should not be used.
An alternate cleaning method is to use one of the products
listed in TP-109* to clean the coils. The cleaners listed are
the only agents deemed safe and approved for use to clean
round tube aluminum coils. TP-109 is also available on the
web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemical
cleaners.

aluminum tube evaporator coil. The safest way to clean the
cleaning practice remains as the recommended cleaning
method for both copper tube and aluminum tube residential
evaporator coils.

21. Start-Up Procedure
WARNING
• Prior to start-up, ensure that all electrical wires are
properly sized and all connections are properly
tightened.
• All panels must be in place and secured. For air tight
application, gasket must be positioned at prescribed
locations to achieve 1.4% leakage.
• Tubing must be leak free.
• Condensate line must be trapped and pitched to allow
for drainage.
• Low voltage wiring is properly connected.
• Auxiliary drain is installed when necessary and
pitched to allow for drainage.
• Unit is protected from vehicular or other physical
damage.
• Return air is not obtained from, nor are there any
return air duct joints that are unsealed in, areas where
or products of combustion such as carbon monoxide
(CO), which may cause serious personal injury or
death.
• Ensure that the equipped R32 sensor is wired to
the furnace PCB and that there are no sources of
potential ignition within the system.

completed.
22. Refrigerant Recovery
When removing refrigerant from a system, either for
servicing or decommissioning, it is recommended good
practice that all refrigerants are removed safely. When
transferring refrigerant into cylinders, ensure that only
appropriate refrigerant recovery cylinders are employed.
Ensure that the correct number of cylinders for holding the
total system charge are available. All cylinders to be used
are designated for the recovered refrigerant and labeled
for that refrigerant (i.e. special cylinders for the recovery of
refrigerant). Cylinders shall be complete with pressure-relief
Empty recovery cylinders are evacuated and, if possible,
cooled before recovery occurs.
The recovery equipment shall be in good working order
with a set of instructions concerning the equipment that
is at hand and shall be suitable for the recovery of the
be consulted. In addition, a set of calibrated weighing scales
shall be available and in good working order. Hoses shall be
complete with leak-free disconnect couplings and in good
condition. The recovered refrigerant shall be processed
according to local legislation in the correct recovery cylinder,
and the relevant waste transfer note arranged. Do not mix
refrigerants in recovery units and especially not in cylinders.
•
• Wait 15 minutes. Some devices in the outdoor unit or
in programmable thermostats will prevent compressor
operation for awhile, and then reset automatically. Also,
some power companies will install devices which shut

on its own.
• Check the electrical panel for tripped circuit breakers or
failed fuses. Reset the circuit breakers or replace fuses
as necessary.
• Check the disconnect switch near the indoor furnace or

by objects (rugs, curtains or furniture).
•
• Listen for any unusual noise(s), other than normal
operating noise, that might be coming from the outdoor
unit. If you hear unusual noise(s) coming from the unit,
If compressors or compressor oils are to be removed,
ensure that they have been evacuated to an acceptable
